Application fiIed'J'une 20, 1910. Serial no; 568,025.

To all whom z'tmay concern Be it known that I, CLARENCE E.- Cox, citizen of vthe United States, residing at Fairfax, in the county of Alchison and State of Missouri, have invented certain new and useful Improvements-in Metallic Tires,

'tions 20 and to prevent the passage of the heat from-the sections 20 to the springs 17 of which the following is a specification.

I .This invention relates to resilient tires} for motor vehicles and the like, and has-for an-objeot to form a metallic tire which is made from flexible material was to obviate the puncturing and flattening of a tire as well as to-form a tire whichwill Withstand considerable wear.

The invention contemplates a tire formed from spring steel which islined with 'wire.

meshing interwoven with wool and asbestos to-reduce the friction between the metallic parts, to provide reinforcing sprin and auxiliary springs within the steel s'ection,'and

to provide the tire with an-oil feeding de--- vice to .'keep the springs from corroling.

The invention has for another obje ctto' form a tire of aplurality of interlocking spring steel sections which carry anti-skid devices to partially overlay the adj acent-secrtions for the purpose of insuring the interlocking of the sections and to thereby strengthen the tire. c v

For a full understanding of the invent-ion reference is to be had to the followingdesc'ription and accompanying drawing, in .which:

Figure 1 is a detail perspective viewof a section ofthe improved tire. Fig.2 is azdetail longitudinal sectional view through the tire. Flg. 3 is a perspective view of one of the interlockingsections detached. Fig; 4c is a detail sectional view of one edge oft-he tire and its: adjacent parts.

Corresponding and like parts are referred to in the following description and indi-' cated in all the views of the accompanying drawing by the same reference characters.

Referring to the drawin'g the improved tire comprises a metallic shell or casing formed of a plurality of interlocking segmentalsect-ions 20 having outturned flanges 21 at their extremities to engage with the rim l1.- The rim 11 is attached in any approved manner to the felly 10. Within the shell, and supported upon the rim'llare a plurality of reinforcing springs 17 extending outwardly-from the rim andrconformi ng in shape to, but being slightly reduced fiin size from the sections 20. A filling 19, reinsprin with thesprings 17 but which do not extend forced by wire-meshing 18, is interposed between the casingsections 20 and the springs 17. The filling 1-9 "is preferably formed from asbestos or other heat non-conductin substance soas to prevent the rubbing of the springs 17 against the inner faces of the sec- The filling 19 is preferably interwoven through the meshing 18'and terminatesadjacent the inner ends of the springs 17 the meshing .18 bein secured against the outer faces of the sprmgsll at their ends. The metallic casing-"is provided with reduced 12 which are arranged alternately from the rim 11 to as great a distance as the springs 17. The springs 12 are adapted toaugment the springs 17' in supporting the load upon the flexing of themetallic casing by the load, or by the sudden jar of; the casing against an obstacle The springs 12 are outturned at their free ends to engage beneath the flanges 21'and the lower edges of the springs17. Bands 15 are arranged beneath the flanges 21 "Of the main casing sections 20 to support the same, and rest upon the upper faces of the rings 13 which are carried against the 11. The outturned flanges of the springs 12 engage beneath the rim s 13 while channelmembers 16 rest upon t upper faces of the bands 15. The channel members 16 have their free ends directed outwardly from the rim -11 and receive therebetween the edges of the springs 17 and the Wire 1 meshing 18, Suitable packing strips 26 are interposed between the casing sections 20 and the channel members 16, as

Well as between the rim 11 and the rings 13. The rings 13 are provided at their outer longitudinal edges with outturned flanges 14 extending beyond the upper faces ofv the flanges 21 to receive retainingstrips23 of =-angular form having the flanges thereof seating-respectively against the sides of-th'ecasing sect-ions '20 and the flange.-21.' Re; taining bolts 24 pass inward-1y through the retainingmembers 23 and the adjacentele ments and receive clampingmuts 25 engaging upon their threaded extremities and. against the inner face of therim 11.,

' The casing sections 20 are provided with anti-skid devices forming retaining means for interlocking the. sections and comprising beads 31 ofW-forml vThe extremities of the beads are of greater thickness than the body Patented Jan, 16,1912.

- tongue 30 a portions thereof and are suitably apertured to receive tapering rivets 32 engaging through the threaded portions of the casing sections 20. The casing sections 20 are each formed by'crimping the section and at its opposite edge withfan inwardly extending aptedto engage in the adjacent roove 29. The ends of the beads 31 proect. slightly beyond the edges of the sections 20 to overhang the grooves 29 and rest against the upper faces of the adjacent sections 20 to retain the tongues 30 within the grooves. The heads 31 thus form an interlocking means between the sections as well as an anti-skidding device upon the tread of the tire. Anv oil-tube 27 extends through the rim 11 and passes inwardly through the telly 10 to support upon its ex tremities .an oil-cup 28 communicating with the tube 27 for feeding a lubricant to the interior of the improved tire.

Having thus'described the invention what 1s claimed as new is 2-'- 1 1. A tire including a plurality of metallic sections each having grooves at one edge provided at one edge with a groove 29 and inturned tongues at its opposite edge, the tongues and the grooves being formed for interlocking engagement, and beads .car-

ried upon the outer faces of the sections and overhanging the grooves to retain the tongues therein. 7

2. A tire comprising sections having interlocking tongues and grooves, and angular beads carried on the sections and having their angular portionscoextending over the tongues and grooves to Hold the same at spaced points from spreadin apart. In testimony whereof, I a my signature in presence oftwo witnesses.
